6. As an exception to the Sections above, you may also
combine or link a “work that uses the Library” with the
Library to produce a work containing portions of the
Library, and distribute that work under terms of your
choice, provided that the terms permit modification
of the work for the customer’s own use and reverse
engineering for debugging such modifications. You must
give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are
covered by this License. You must supply a copy of this
License. If the work during execution displays copyright
notices, you must include the copyright notice for the
Library among them, as well as a reference directing the
user to the copy of this License. Also, you must do one
of these things:
a) Accompany the work with the complete corresponding
machine-readable source code for the Library including
whatever changes were used in the work (which must
be distributed under Sections 1 and 2 above); and,
if the work is an executable linked with the Library,
with the complete machine readable “work that uses
the Library”, as object code and/or source code, so
that the user can modify the Library and then relink to
produce a modified executable containing the modified
Library. (It is understood that the user who changes
the contents of definitions files in the Library will not
necessarily be able to recompile the application to use
the modified definitions.)
b) Use a suitable shared library mechanism for linking
withthe Library. A suitable mechanism is one that (1)
uses at run time a copy of the library already present
on the user’s computer system, rather than copying
library functions into the executable, and (2) will operate
properly with a modified version of the library, if the
user installs one, as long as the modified version is
interface-compatible with the version that the work
was made with.
c) Accompany the work with a written offer, valid for at
least three years, to give the same user the materials
specified in Subsection 6a, above, for a charge no
more than the cost of performing this distribution.
d) If distribution of the work is made by offering access
to copy from a designated place, offer equivalent
access to copy the above specified materials from the
same place.
e) Verify that the user has already received a copy of
these materials or that you have already sent this user a
copy. For an executable, the required form of the “work
that uses the Library” must include any data and utility
programs needed for reproducing the executable from
it. However, as a special exception, the materials to be
distributed need not include anything that is normally
distributed (in either source or binary form) with the
major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless
that component itself accompanies the executable.
It may happen that this requirement contradicts the
license restrictions of other proprietary libraries that do
not normally accompany the operating system. Such a
contradiction means you cannot use both them and the
Library together in an executable that you distribute.
7. You may place library facilities that are a work based on
the Library side-by-side in a single library together with
other library facilities not covered by this License, and
distribute such a combined library, provided that the
separate distribution of the work based on the Library and
of the other library facilities is otherwise permitted, and
provided that you do these two things:
a) Accompany the combined library with a copy of the same
work based on the Library, uncombined with any other
library facilities. This must be distributed under the terms
of the Sections above.
b) Give prominent notice with the combined library of the
fact that part of it is a work based on the Library, and
explaining where to find the accompanying uncombined
form of the same work.
8. You may not copy, modify, sublicense, link with, or
distribute the Library except as expressly provided under
this License. Any attempt otherwise to copy, modify,
sublicense, link with, or distribute the Library is void,
and will automatically terminate your rights under this
License. However, parties who have received copies,
or rights, from you under this License will not have their
licenses terminated so long as such parties remain in full
compliance.
9. You are not required to accept this License, since you
have not signed it. However, nothing else grants you
permission to modify or distribute the Library or its
derivative works. These actions are prohibited by law if
you do not accept this License. Therefore, by modifying or
distributing the Library (or any work based on the Library),
you indicate your acceptance of this License to do so,
and all its terms and conditions for copying, distributing or
modifying the Library or works based on it.
10. Each time you redistribute the Library (or any work based
on the Library), the recipient automatically receives a
license from the original licensor to copy, distribute, link
with or modify the Library subject to these terms and
conditions. You may not impose any further restrictions
on the recipients’ exercise of the rights granted herein.
You are not responsible for enforcing compliance by third
parties with this License.
11. If, as a consequence of a court judgment or allegation of
patent infringement or for any other reason (not limited to
patent issues), conditions are imposed on you (whether by
court order, agreement or otherwise) that contradict the
conditions of this License, they do not excuse you from
the conditions of this License. If you cannot istribute so as
to satisfy simultaneously your obligations nder this License
and any other pertinent obligations, then as a consequence
you may not distribute the Library at all. For example, if a
patent license would not permit royalty free redistribution
of the Library by all those who receive copies directly or
indirectly through you, then the only way you could satisfy
both it and this License would be to refrain entirely from
distribution of the Library.
If any portion of this section is held invalid or unenforceable
under any particular circumstance, the balance of the section
is intended to apply, and the section as a whole is intended
to apply in other circumstances.
It is not the purpose of this section to induce you to infringe
any patents or other property right claims or to contest
validity of any such claims; this section has the sole purpose
of protecting the integrity of the free software distribution
system which is implemented by public license practices.
Many people have made generous contributions to the
wide range of software distributed through that system
in reliance on consistent application of that system; it is
up to the author/donor to decide if he or she is willing to
distribute software through any other system and a licensee
cannot impose that choice. This section is intended to make
thoroughly clear what is believed to be a consequence of the
rest of this License.
